T. Gianetti received the 2021 Cottrell Scholars Award

Recipients are chosen through a rigorous peer-review process of applications from top research universities, degree-granting research institutes, and primarily undergraduate institutions in the United States and Canada. Their award proposals incorporate both science education and research.

We report the reactivity between the water stable Lewis acidic trioxatriangulenium ion (TOTA+) and a series of Lewis bases such as phosphines and N-heterocyclic carbene (NHC). The nature of the Lewis acid–base interaction was analyzed via variable temperature (VT) NMR spectroscopy, single-crystal X-ray diffraction, UV-visible spectroscopy, and DFT calculations.

Redox flow batteries (RFBs) represent a promising technology for grid-scale integration of renewable energy. However, cross-contamination problems, encountered with distinct catholyte and anolyte, limit the development of reliable organic RFBs. Herein, we report the first use of a helical carbocation with three oxidation states, for the development of symmetric cells.

T. Gianetti received the 2021 Thieme Chemistry Journal award

The Thieme Chemistry Journals Award is presented every year to up-and-coming researchers worldwide who are in the early stages of their independent academic career as an assistant or junior professors. The awardees are selected exclusively by the editorial board members of SYNTHESIS, SYNLETT, and SYNFACTS who constantly watch out for promising, young individuals working in chemical synthesis and catalysis or closely related areas of organic chemistry."​​

Persistent organic radicals have gained considerable attention in the fields of catalysis and materials science. In particular, helical molecules are of great interest for the development and application of novel organic radicals in optoelectronic and spintronic materials. Here we report the syntheses of easily tunable and stable neutral quinolinoacridine radicals under anaerobic conditions by chemical reduction of their quinolinoacridinium cation analogs

Red light has the advantages of low energy, less health risks, and high penetration depth through various media. Herein, a helical carbenium ion (N,N′-di-n-propyl-1,13-dimethoxyquinacridinium (nPr-DMQA+) tetrafluoroborate) has been used as an organic photoredox catalyst for photoreductions and photooxidations in the presence of red light (λmax = 640 nm).

A new library of phosphonium salts has been synthesized from the reaction of tris‐(2,6‐dimethoxyphenyl)carbenium with different phosphines. All these phosphoninum salts were efficient phase‐transfer catalysts for alkylation of 1,3 dicarbonyl compounds. One compound, a bifunctional phosphonium salt, prepared from tris‐(2,6‐dimethoxyphenyl)carbenium and an aminophosphine, was found to be an efficient catalyst for CO2 fixation reactions with epoxides under mild conditions.

The synthesis of novel redox active ambiphilic ligands L1–L3 and their coordination chemistry to first-row late transition metal halides (M = Co and Ni) is reported. The heterocyclic carbocation scaffolds act as Lewis acid moieties while the pyridine anchor acts as the coordinating Lewis base. The high synthetic tunability of this ligand scaffold allows for control of its rigidity and electronic properties.

Congrats to Mubarak for his excellent 2nd year Seminar
